Answer:
it's 42 my bad...
Step-by-step explanation:
1) 3/5=9/x (cross multiply<span>)
3x=5(9)
3x=45
x=15
2) </span>2/4=x/12 (cross multiply<span>)
</span> 2(12)=4x
24=4x
<span> 6=x
</span>3) 10/x=5/9 (cross multiply<span>)
10(9)=5x
90=5x
18=x
</span>
4) 5/6=x/18
5(18)=6x
90=6x
x=15
Given:
6 out of 15 customers order a chicken sandwich
270 customers
This is a problem of ratio and proportion:
a/b = c/d where ad = bc
6/15 = x/270
6 * 270 = 15x
1,620 = 15x
1620 / 15 = x
108 = x
The restaurant should predict to serve 108 chicken sandwich to the 270 people.

1 adjacent side BC
---------- = cot B = ----------------------- = ---------
tan B opposite side AC
